Abstract

A sub-surface root fertilization apparatus for use in injecting the soil with a concentrated liquid fertilizer comprising a frame, a portion of the frame adapted to receive at least one tank, at least one tank within this portion, a pump mounted on the frame having an inlet and an outlet, a tube communicating one of the tanks with the input of the pump, control means for operating the pump, a probe having a mounting chuck at one end, a fluid passage within the probe, the fluid passage terminating in a nozzle means at the end of the probe opposite the mounting chuck, a tube mounted on the probe communicating the probe with the outlet of the pump and an impact hammer attached to the mounting chuck of the probe.

Claims

1. A probe for use with a sub-surface root fertilizer comprising a generally cylindrical body having one generally conical end;

a mounting chuck at the end of said body opposite said conical end;

a centrally disposed central passage within said body extending substantially the length of said body having inlet means and outlet means, said inlet means communicating with a hose communication near said mounting chuck, said outlet means comprising at least one aperture through said body near said conical end, the axis of said aperture being at an angle with respect to the axis of said passage;

a first circumferential notch on the surface of said body at the outlet of said aperture; and

at least two O-rings seated in said notch covering said apertures, each ring being in contact with said notch, said Orings being in side-by-side relationship so that fluid under pressure passing through said apertures will pass between said Orings.

2. The probe of claim 1 wherein said central passage includes four apertures through said body.

3. The probe of claim 1 wherein there are two flexible O-rings.

4. The probe of claim 1 wherein said probe has a removable tip.

5. The probe of claim 1 wherein said hose connection is barbed.

6. The probe of claim 1 wherein said central passage additionally includes at least one added aperture through said body farther from said conical end than said circumferential notch and an expandable member mounted on said body completely covering the outlet of said added aperture.

7. The probe of claim 6 wherein said expandable member is mounted within a circumferential recess and is held in said recess by two stainless steel bands.

8. The probe of claim 6 wherein said passage for fluid flow includes four apertures through said body.

9. A tip for use with a sub-surface root fertilizer probe having a central passage for fluid flow comprising a body having a conical end and an end adapted to be connected to said probe, a central passageway within said body extending substantially the length of said body, said passageway having inlet means and outlet means, said inlet means adapted for communication with said central passage, and said outlet means comprising at least one aperture through said body, the axis of said aperture being at an angle with respect to the axis of said passageway, a circumferential notch on the surface of said body at the outlet of said aperture, at least two O-rings seated in side-by-side relationship in said notch covering said aperture, each O-ring being in contact with said notch, so that a fluid under pressure passing through said aperture will pass between said O-rings.

10. The tip of claim 9 wherein said central passage includes four apertures through said body.

11. The tip of claim 9 wherein there are two O-rings.
